Objective: To be able to draw bar charts

I collected the results in a TALLY CHART. The data Last night I stood on Fulwood road for 5 mins and counted the different types of transport that passed me. I collected the results in a TALLY CHART. Type of transport Tally frequency Car Bus Motor bike Bike other 18 5 2 3 5

From this data I can draw a BAR CHART Type of transport Frequency Car 18 Bus 5 Motor bike 2 Bike 3 Other From this data I can draw a BAR CHART You need to add a title and label the axis

Pie Charts Be able to construct a pie chart from a collection of data, using a protractor.

Makes of car in a school car park Toyota Ford Citroën Volvo Frequency 3 2 4 1 Construct a pie chart to show this information. A full circle is 360o There are a total of 3+2+4+1 = 10 cars We use 36o to represent each car 360o

Makes of car in a school car park Toyota Ford Citroën Volvo Frequency 3 2 4 1 Angle in pie chart 3x36o =108o 2x36o =72o 4x36o =144o 1x36o =36o We use 36o to represent each car so the 3 Toyotas are represented by 3x36o = 108o Work out the angle needed for each of the other models of car

Makes of car in a school car park Toyota Ford Citroën Volvo Angle 108o 72o 144o 36o Mark the centre of the pie and draw the circle. Draw a line from the centre to the edge Measure the first angle needed (108o) Draw in the line and label the section Toyota 108o

Makes of car in a school car park Toyota Ford Citroën Volvo Angle 108o 72o 144o 36o From this line measure the next angle, draw the line and label the section. Continue in this way Check that the last section has the correct angle and label it. Volvo Toyota Citroën Ford

Why? Why do we use 36o to represent 1 car? What would happen if there were 20 cars? What about 60 cars? Or 15 cars? If there were 20 cars in your survey, what angle would you use to represent 4 cars? 7 cars? 12 cars?
